Hamas on Sunday called for a swift start to a hostage-prisoner exchange with Israel as negotiators from the two warring sides meet in Egypt for crucial talks aimed at ending the nearly two-year war.

Foreign ministers of several countries, including Egypt, said the talks were a "real opportunity" to achieve a comprehensive and sustainable ceasefire in Gaza.

"Hamas is very keen to reach an agreement to end the war and immediately begin the prisoner exchange process in accordance with the field conditions," a senior Hamas official told AFP on condition of anonymity.

The diplomatic push follows the Palestinian militant group's positive response to U.S. President Donald Trump's roadmap for the release of captives in exchange for Palestinians held in Israeli jails.

Negotiators are taking place in Egypt's Red resort of Sharm El-Sheikh, with Israeli Prime Minister Benjamin Netanyahu expressing hope that hostages held in Gaza could be released within days.

Netanyahu said on Saturday he had instructed negotiators to go to Egypt "to finalise the technical details", while Cairo confirmed it would also be hosting a delegation from Hamas for talks on "the ground conditions and details of the exchange of all Israeli detainees and Palestinian prisoners."
